Acusa: Sacred Epicinean desert plant, growing only in Deserta Primerta. Emits phosphorescent glow and stays in anhydrobiosis (living without water) for 10 year cycles. Upon conclusion of 10 years, Acusa blooms with many reddish blossoms, which, when prepared, contain hallucinogen used by Custodial Apprentice in Apprentice Installation Ceremony.

The Acusa's blossoms are enticing, but its spines are threatening.
